What to check first
Can I keep using it?
Do not keep using the appliance while this warning is active.
Do not keep running the appliance when water is visible, a leak warning is active, or water could reach wiring or controls.
- Safe next step
- Stop the cycle if safe, turn off water when appropriate, protect the floor, and avoid repeated resets until the leak source is understood.
- Stop when
- Water is near wiring, cabinetry is getting wet, the leak returns, or the source is not safely visible.
Do not keep using the appliance if the code points to voltage, wiring, control power, burning smell, smoke, or a possible miswired supply.
- Safe next step
- Use only safe owner-level power checks, then involve a qualified technician or electrician when the source points to wiring or supply voltage.
- Stop when
- Breakers trip, lights dim, the appliance smells hot, wiring may be miswired, or the warning returns after a safe reset.
Safety boundaries
Safe first
- Match the exact brand, appliance type, and displayed code first.
- Use the model manual as the final authority for access steps.
- Stop and address visible water before retrying the appliance.
- Disconnect power before any service-access step.
Do not do this
- Do not keep running the appliance while this code is active.
- Do not open drain or pump areas while the appliance is powered.
- Do not bypass locks, float switches, leak sensors, or other safety systems.
Common causes include
- Food soils built up in the dishwasher sump
- Glass trap or filter clogged with food debris
Basic checks
- Look for standing water after the cycle stops; if water remains, leave the dishwasher off and skip another cycle.
- Inspect the glass trap and filter only with power off and the tub cool; if food soils are visible, clean them as the model guide describes.
- Reinstall the glass trap and filter exactly as the model guide shows; if either part will not seat normally, stop rather than force it.
- Run one empty rinse or short cycle only after safe cleaning; if i40 returns or water remains, stop and arrange service.
Reset or retry steps
- Electrolux says to clean the glass trap and filter, then rerun the dishwasher once; stop if i40 returns.
When to call a technician
- Contact service if i40 returns after the glass trap and filter are cleaned as the model guide describes.
- Stop and arrange service immediately if water leaks, an electrical odor appears, or broken glass prevents safe filter access.
Before approving a paid visit, check warranty status and reviewquestions to ask before repair.
FAQ

Do not keep using the appliance until the visible issue has been checked and the relevant safety warnings have been addressed. Switch off dishwasher power before reaching into the filter area.
When should I call a technician for Electrolux i40?
Contact service if i40 returns after the glass trap and filter are cleaned as the model guide describes. A qualified technician may check Glass trap, Filter, and Drain sump against the model's service information before treating any part as failed.
